JAMES B. MARQUIS, OF NORWICH, NEW YORK.

CH EESE-VAT.

SPECIFICATION formingpart of Letters Patent No. 228,366, dated June 11880.

Application filed October 10, 1879.

To all whom it may concern:

Be it known that I, JAMES B. MARQUIS, of Norwich, in the county ofOhenango, and in the State of New York, have invented certain new anduseful Improvements in Gheese-Vats and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making a part of thisspecification, in which Figure 1 is a perspective view of my improveddevice as arranged for use. Fig. 2 is a vertical cross-section of thesame, the dotted lines showing the position of parts when the heater isswung to one side. Fig. 3 is a like View of said device, showing theposition of parts when said heater is raised; and Fig. 4 is a centrallongitudinal section of said heater upon a vertical line.

Letters of like name and kind refer to like parts in each of thefigures.

The design of my invention is to enable curd for cheese to be moreeasily and quickly prepared; and to this end it consists, principally,in a cheese-vat provided with a heater, which may be swung from side toside within its interior, substantially as and for the purposehereinafter specified.

It consists, further, in a cheese vat provided with a heater, which maybe adjusted vertically and swung from side to side within its interior,substantially as and for the purpose hereinafter shown.

It consists, further, in combining with a vat for containing liquids aheater in which a circulation of water within its interior is pro ducedby means of a current of steam admitted into a chamber located withinsaid heater and open to the admission and exit of water, substantiallyas and for the purpose hereinafter set forth.

It consists, further, in the construction of the heater, by means ofwhich a continuous circulation of water is effected around the interiorof its exterior wall, substantially as and for the purpose hereinaftershown.

It consists, further, in the means employed for oscillating said heaterwithin the vat, substantially as and for the purpose hereinafter setforth.

It consists, further, in the means employed for locking the heater invertical position, substantially as and for the purpose hereinaftershown and described.

It consists, finally, in the device as a whole, its several parts beingcombined to operate in the manner and for the purpose substantially ashereinafter specified.

In the annexed drawings, A represents a vat, constructed from sheetmetal, with a semicircular bottom and vertical ends. Said vat ispreferably inclosed in a wooden casing, B, and supported by means offourlegs, O. Supported within suitable bearings D, arranged over eachend of the vat A, is a shaft,E, which, at or near its center, has across-arm, c, that extends horizontally and transversely to equaldistances, and at the same point is provided with a second arm, 6, thatextends upward at a right angle to said arm 0.

Within the vat A is placed a heater, F, which has a cylindrical form andextends lengthwise of said vat nearly to its ends. At one end saidheater is provided with two pipes, f and f, that at their lower endscommunicate with its interior, and from thence extend upward to a pointabove the edge of said vat, and at such point are provided with an eye,00, while at its opposite end said heater has attached a bar, f thatextends upward to .apoint upon a line with the upper ends of said pipes,and terminates in an eye, 00, similar to the eyew, to each of which eyesa cord or chain is attached.

From the eyes 00 and .00 two cords, G, pass upward over suitablepulleys, I, and thence downward at one end of the vat to and around ashaft, K, that is journaled within suitable bearings upon the casing B,and is provided at one end with a crankflc, by means of which it may berotated.

The mechanism described enables the heater F to be suspended within thevatA and to be raised or lowered to any desired point, after whichvertical adjustment said heater islocked in place by moving the shaft Klongitudinally until its crank It bears against theend of the casing Band prevents said shaft from rotating, as shown by the full lines ofFig. 1.

Extending lengthwise of the heater F, at a point slightly above itsupper side, is a vertical flange, F, from which, at opposite sides ofits longitudinal center, cords f extend upward to and are connected withthe outer ends of the arms 0 of the shaft E, the arrangement being suchas to enable said heater to be swung from side to side within the vat Aby a partial rotation of said shaft in opposite directions when saidheater is at the lower limit of its motion and said cords are taut.

It is intended that several vats shall be arranged side by side, and thearms a of each shaft E connected to a bar that passes over the entireseries, and is caused to reciprocate longitudinally, and so as to causeeach of said shafts to oscillate within its bearings, such motion beingcontinuous. In such event it will only be necessary to raise the heaterF until the cords f are slackened, as seen in Fig. 3, in order to arrestthe motion of said heater, while by lowering the latter until said cordsare taut again the motion of said shaft will be again communicated, andsaid heater caused to swing to and'fro within its "at.

It is intended that the heater F shall be suspended at a point justbelow that to which the curd will extend when separated from the whey,the flange F being within the space to be occupied by the curd, and inoperation it is found that the motion of said heater causes a movementof the whey from each side of the vat downward and toward the center assaid heater moves toward the same, such move ment being best adapted forthe purpose of the separation of the whey from the curd.

The operation of the flange F is to thoroughly agitate the curd andbreak the same into small pieces, so as to facilitate the removal of thewhey.

The heater F is intended for use with steam, which is admitted through aflexible pipe to the pipe f, which passes downward nearly to the bottomof said heater, and then turns horizontally inward, and terminateswithin the open end of a cylindrical tube, F that is placed within thelower portion of the interior of said heater.

The end of the tube F farthest from the pipe f is open, and terminates ashort distance from the contiguous end of the heater F, so that if acurrent of steam is admitted through said pipe f it will pass to and outof the farther end of said tube F and carry with it such water caused bycondensation as is contained within the latter.,

\Vhen, as soon occurs, the heater F becomes filled with water, theoperation of the inflowing current of steam is to cause the water withinthe tube F to move to and escape from its opposite end into the spacebetween said tube and the heater F, from whence said water movesbackward to and again enters the induction end of said tube, themovement described being continuous, and its rapidity governed by thevolume and velocity of the current of steam. a

The heat of the steam is imparted to the water within the tube F and assaid water is caused to circulate rapidly through the heater F everyportion of.tl1e latter is heated, and its temperature is practicallyuniform over its entire surface.

My method of imparting heat to the contents of the vat rendersimpossible the burnin g of the milk, (a result which always follows thecontact of milk with pipes or heaters containing live steam,) andenables the temperature of said milk to be easily and with certaintyregulated, so as to cause the cooking and separation of the curd fromthe whey to be effected in the most perfect and expeditious manner.

The pipe f being connected by a flexible tube with a waste-pipe orreservoir, the surplus water caused by the introduction of steam to theheater is permitted to escape by overflow.

Having thus fully set forth the nature and merits of my invention, what1 claim as new 1s 1. A cheese vat provided with a heater which may beswung from side to side within its interior, substantially as and forthe purpose specified.
